Over the past 20 years, the MIPS® architecture has continually evolved, but the standard definition of the architecture has remained simple, streamlined and highly scalable. The initial processors we developed based on the architecture excelled in a wide range of high-performance applications, from supercomputers to embedded controllers, beginning with the 8 MHz, 32-bit R2000 processor, based on the MIPS I™ architecture. Subsequent processors included the R3000®, the 64-bit R4000™, and the R5000®, R10000® and R12000®, many of which were developed while MIPS Technologies was part of Silicon Graphics, Inc. (SGI). Below are historical documents that offer technical information on the MIPS-Based® "R" Series of products.
